Fraternity Rush at TCU

Hi there,
I am a high school student currently looking at different colleges, and I will definitely want to join a fraternity. I go to a private SPC school in Texas (think Episcopal, FWCD, Kinkaid), and was wondering about the fraternity rush process at TCU. From my understanding, the rush process is informal at TCU and most of it happens during the before freshman year.

I know 2 girls in sororities at TCU, and besides that have no connections to greek life at TCU. Last year, my high school sent 7 guys to TCU and I am guessing that most or all joined fraternities.

Does anyone know how the fraternity rush process works at TCU, or do you have any advice for someone like me (coming from a reputable school, but basically no connections).

Thanks for your help.
